20100236622 | REFLECTIVE LIGHT WAVELENGTH MODULATOR - A reflective light wavelength modulator includes a reflection module with a reflective arc surface, at least one thermal conducting column installed at the reflective arc surface, at least one optoelectric conversion module, particularly an illumination module, a solar cell or an photocell, installed on a distal surface of the thermal conducting column, and a reflective mask installed at an appropriate distance from the optoelectric conversion module. The reflection module or the reflective mask is made of a wavelength modulation material, such that when the light produced by the optoelectric conversion module or the received light source is reflected from the reflective mask, the wavelength of the light source is changed to achieve the effects of providing a wavelength modulation function of a light source with a color and a cost-effective optoelectric equipment. | 09-23-2010 |
20080302977 | Light emitting module for producing a visible light by passive ultraviolet excitation - A light emitting module for producing a visible light by passive ultraviolet excitation includes an excitation light source member and at least one layer of wavelength modulation matrix. The excitation light source member produces an ultraviolet light with a specific wavelength range. The wavelength modulation matrix adopts an organic polymer as a carrier, and the carrier adds a composite material composed of an organic wavelength modulation material, a quantum dot luminescence color rendering modulation material and a nanoparticle brightness enhancement luminescence powder, and the composite material is cured and formed by coating, injection molding, thin film lamination, screen printing or thick film printing, so that when the wavelength modulation matrix is projected by an ultraviolet light beam emitted by the excitation light source member, a light including a visible light is produced. | 12-11-2008 |
